Recently, MSCs isolated from bone marrow (bmMSCs) were shown to be a blend of distinct cells and MSCs isolated from different tissues show besides some common features also some significant differences. (hindawi.com)
We therefore briefly discuss differences found in subsets of human bmMSCs and in MSCs isolated from some other sources and touch upon how this could be utilized for cell-based therapies. (hindawi.com)
The MSCs have been described for the first time as colony forming fibroblasts (CFU-F), a rare population of cells residing in the bone marrow of guinea-pigs or mice [ 1 , 2 ]. (hindawi.com)
